Material & Finish
Voltage Rating: Blocks meet 600 volt
creepage and clearance requirements of
NEMA, UL and CSA for general
industrial control equipment and
panelboards. Withstand voltages greatly
in excess of IEEE switchgear standards
for 750 volts.
Ampacity: For a single #4 AWG wire
the maximum amperage recommended
is 85 amps.
Standard Contacts:
Material: Electrical grade copper or
copper alloy conductor. Steel Screws
plated to resist corrosion in most
industrial applications
AL-CU Tubular Screw: Aluminum
compatibility with aluminum or copper
conductors. AL-CU is tin-plated brass.
Environmental Contacts
(for highly corrosive
atmospheres)
Tubular Screw: Electrical grade
copper tube with nickel plating. Nickel
plated brass screws.
